Like a strand of mutating DNA, a deadly conspiracy winds its way
through the entire Alpha Quadrant

Long Synopsis:

Like a strand of mutating DNA, a deadly conspiracy winds its way
through the entire Alpha Quadrant, just as it stretches across several
years of Starfleet history -even to the Cardassian space station that
will someday be known as Deep Space Nine .
A virulent plague has stricken Terok Nor, striking down both the
enslaved Bajorans and Cardassian oppressors, who blame each other for
the growing epidemic. Dr. Katherine Pulaski, late of the Starship
Enterprise , must work with the tyrannical Gul Dukat, as well as a
rebel spy named Kira Nerys, to discover the true source of an infection
that threatens them all!

"Who are you?" Dr. Pulaski asked.
"My name doesn't matter," Kira Nerys said. "And I don't have a lot of
time, so please listen to me. I would like you to come with me to
Bajor."
Pulaski frowned. "I've already been through this with Gul Dukat. I'm
afraid I can't leave the station."
"He doesn't have to know," Kira said. "I'll smuggle you down there and
I'll bring you back."
Pulaski held up her hand. "I'm sorry," she said.
"No." Kira clenched her fists. "I won't take no for an answer. I
won't. We need you."
